Title: Hippocampus-associated proteins, dna sequences coding therefor and uses thereof
Inventor: STAPLETON GENEVIEVE
IPC: A61K35/76
Filed: 1995-10-18
Abstract: This invention provides novel hippocampus-associated proteins and DNA sequences coding therefor. In an investigation of hippocampus-associated proteins by differential screening of a rat hippocampus cDNA library, a cDNA species encoding a novel protein designated Hct-1 was isolated and shown to be related to cytochromes P450.

Title: Device for winding a wrapping film around an article to be packaged
Inventor: SUOLAHTI YRJO
IPC: B65B11/02
Filed: 1997-08-20
Abstract: Device for winding a wrapping film around an article (1) to be packaged, the article to be packaged having the shape of a substantially flat rectangle in cross-section. The article to be packaged comprises two substantially parallel broad sides (2, 3) and two narrow sides (4, 5), the edges between the broad and narrow sides forming supporting points (6) for the wrapping film. The device comprises a film distributor (7) disposed to travel along a ring-like endless track (8) at a substantially constant speed around the article to be packaged. The track (8) of the film distributor (7) is so formed that the track radius (r) from the track to the supporting point (6) increases continuously at least in the track area (S) where the film portion (12) drawn from the roll in the direction of the radius and stretched between the film distributor and the supporting point (6) approaches a position parallel to at least one broad side (2, 3) of the article being packaged, such position corresponding to a point (0) where a straight line in the direction of the broad side intersects the track (8), so that, when the point (0) is being approached and at the point, a tangent (T) to the track is at a smaller angle to the straight line in the direction of the broad side than a tangent to an imaginary circular path, the rate of increase of the radius (r) at least in the area of the track and the rate of delivery of film from the film roll (9) being higher than if the track followed the imaginary circular path mentioned.      At and after the point (0) on the track, the rate of increase of the radius (r) remains substantially the same as before point (0), with no substantial changes occurring in the rate of increase of the radius.

IPC: G09G3/28
Filed: 1996-04-02
Abstract: In a subfield drive method, two subframes of the least brightness are arranged adjacently to each other to select and light up the display device in terms of the change in image brightness in the time axial direction. When, for example, the level of original signal changes from 7 to 8 or from 8 to 7, SF3, SF2, SF1 and SF1 are selected as subframes for level 8, and SF3, F2 and SF1 are selected as subframes for level 7.      This prohibiting any continuous lighting or non-lighting at the levels 7 and 8, there is no substantial change in brightness nor degradation of picture quality at that time. Any distortion of moving image (pseudo contour) is removed by the correction circuit 20 having the frame memory 24 that delays by one frame, the correction constant set circuit 26 that outputs correction data, and the adder 28 that adds the correction data to the original image signal.

Abstract: I call my invention the Portable coffee, tea and hot chocolate maker. Starting from the bottom up I will give a description of my invention. On the bottom of the mug is a removable (screw off) condiment holder. There are four sections to the condiment holder. One for coffee bags, tea bags, hot chocolate packages and the last one is for sugar and cream. Next is the battery-powered heater. This is built inside the cup and operated by flicking a switch underneath mug. This switch is located in between the mug part and the condiment holder. On the side of the mug is a long, vertical shaped carrying compartment for the hard plastic stirrer. At the bottom of the stirrer is a small hook. The handle of the mug is circular and a portion of it can be removed to allow it to act as a clip for a bag. It is best illustrated if one was to think of a toilet roll holder. The interior part can be pushed into the exterior part. Inside the mug there is two vertical incisions ranging from the top of the cup to the bottom. In these two incisions is where the "filter bag holder" is placed. The filter bag holder is a small component of the invention, which acts like a coffee filter. In this holder like compartment is placed either a coffee or tea bag. As well there is a hook on the top of the holder which allows it to be removed after use. Once the water has reached it's desired temperature a bag is placed inside the compartment and into the mug using the vertical incisions as holders. The water must first pass through the bag to reach the other side of the mug. Once the filter bag holder has reached the bottom the consumer uses the hard plastic stirrer with the hook at the bottom to remove the filter bag holder. The lid is removable by screwing it off and there is a small hole which can be covered if someone chooses to drink with the lid on.

Title: Method and a block carton blank for the lining of freezing frames
Inventor: NIELSEN MOGENS
IPC: B31B1/74
Filed: 1996-08-05
Abstract: When placing block carton linings in freezing frames it is important that the existing comer flaps (20, 27) on the carton insertion are placed externally on the adjoining side panels (8), so that they cannot be frozen when sticking into the material filled into the lined freezing frame. During a fast mounting of the block carton it may be difficult to perceive whether these comer flaps are placed inwardly or outwardly of the adjoining carton sides, since they visibly will become indistinguishable in relation to the surroundings. By the invention this will be changed, so that the inwardly facing sides of the corner flaps (20, 27) are made with a surface characteristic, e.g. a distinct signal colour, which is deviating in such a way from the outlook of the rest of the inside of the carton, that a faulty placing of the corner flaps will be discovered instantly by sight.
Patent CA-2228978-A1 (CA)
Inventor: MCNAUGHTON JOHN PETER
IPC: A61B5/087
Filed: 1998-02-03
Abstract: A peak flow meter has an element (4) displaceable along a hollow body (2) by the exhalation of a subject, and means for indicating the maximum displacement of that element as a measure of peak flow.  Pre-set markers (20) are located at selected positions to indicate selected displacement values.  The markers are in the form of elements that are snap-fitted onto the meter body at chosen positions and they have a toothed interengagement (12,28) with the body as they snap-fit into place.  Accidental or careless movement of the markers is thereby precluded while permitting ready placement when required

Title: Pipe anchoring system
Inventor: KAMPF MARK
IPC: F16L3/24
Filed: 1998-02-10
Abstract: A system for anchoring a pipe, such as a train pipe, to the inside of an elongated right angle structural part or member, such as may be mounted on a sidewall of a rail car. The elongated right angle structural part has a plurality of spaced bolt receiving holes extending through one leg and a plurality of pipe anchor bases, with brackets fastened thereto, axe attached to the right angle structural member by means of a single bolt extending through a bracket and one of the spaced bolt-receiving holes. Each pipe anchor base may be. of the general type found in known pipe anchors as disclosed, for example, in U.S. Patent No. 2,546,792 dated March 27, 1951, U.S.      Patent No. 2,625,354 dated January 13, 1953 and U.S.      Patent No.' 4,222,538 dated September 16, 1980. Once a combined pipe anchor base and its bracket has been installed on the inside of the right angle structural part, relative movement between the anchor base-bracket combination and the structural part will be prevented.      Each bracket will have a pair of openings, one of which will be exposed and the other will be covered or blinded when the bracket is secured to an anchor base in one position and this relationship will be reversed when the bracket is secured in a different position on the bracket.      Thus, the anchor base-bracket combinations can be left-handed or right-handed.
